The trouble is that if libpng is not available, all this functionality would disappear (not just for pngs, but also for gifs or whatever other images *are* supported). It is ok if libpng is required. We need not bend over backwards to support its absence. Anyone can install it, after all. Or we could make libpng required for image support.
